What Is a Tyre Camber? A Beginner’s Guide to Understanding Wheel Alignment

When it comes to maintaining your vehicle, tyre alignment is often overlooked. Yet, it plays a crucial role in how your car handles, how long your tyres last, and even how smooth your ride feels. One of the key aspects of wheel alignment is tyre camber. But what exactly is tyre camber, and why does it matter? Let’s break it down.

Understanding Tyre Camber 

Tyre camber refers to the angle at which the wheels and tyres tilt when viewed from the front or back of the vehicle. If you’ve ever noticed that your tyres are slightly tilted inward or outward instead of standing perfectly upright, that's camber at play.

Types of Tyre Camber:

  • Positive Camber: The top of the tyre leans outward, away from the vehicle.
  • Negative Camber: The tyre's top is leaning inside, towards the vehicle.
  • Zero Camber: The tyre is perpendicular to the ground, neither tilted nor lean.

Why Is Camber Important?

The camber angle affects the way your tyres touch the ground. The appropriate camber angle will have your tyre tread level on the road, giving the best traction and wear.

Positive Camber:

  • Found in most older cars and farm equipment.
  • Assists in ensuring stability when driving in a straight line.
  • Reduces steering force, but too much positive camber will cause uneven tyre wear.

Negative Camber:

  • Used in sports cars and high-performance vehicles.
  • Improves cornering traction by providing more contact during cornering.
  • Too much negative camber, however, will wear out the inner edges of tyres.

Zero Camber:

  • Perfect for ensuring even tyre wear.
  • Used for straight-line driving with equal traction.

The Science Behind Camber

Camber is the product of the suspension geometry of the vehicle. When the suspension flexes or stretches, the camber angle will vary slightly. This dynamic effect assists in providing optimum contact between tyre and road, even during the condition of turning or bouncing over bumps.

The optimum camber angle is dependent upon the vehicle type and its purpose. For example, performance vehicles tend to have a very slight negative camber to enhance grip under hard cornering, but family saloons typically have close to zero camber for stability and uniform tyre wear..

How to Recognize Camber Problems

It isn't always that simple to find camber issues by looking at them. Yet, there are some common symptoms that demonstrate that something is wrong:

  • Uneven Tyre Wear: If you see the inner or outer edges of your tyres wearing out quicker than the center, it may be a camber problem.

  • Vehicle Pulling to One Side: Camber misalignment can make your vehicle pull left or right, making it more difficult to drive straight.

  • Unstable Handling: If your vehicle handles in a wobbly or less responsive manner when cornering, it could be because of improper camber settings.

  • Higher Rolling Resistance: Camber that is out of alignment causes tyres not to roll as well, which results in higher fuel usage.

What Leads to Camber Issues?

Some issues can cause camber misalignment:

  • Crashes or Collisions: Even slight bumps can warp suspension parts.

  • Worn-out Suspension Parts: Ball joints and control arms may wear out, causing alignment issues.

  • Road Potholes and Hazards: Running into a curb or a large pothole can upset camber settings.

  • Modifications: Reducing or raising your vehicle without altering the camber is likely to throw it off.

  • Poor Installation: At times, if the suspension parts are installed poorly, they may influence the camber angle.

 

The Effect of Camber on Tyre Life

Inaccurate camber settings result in uneven tyre wear, particularly if the camber angle is excessively positive or negative. Unevenly worn tyres not only compromise safety but also increase replacement frequency, contributing to increased maintenance expenses.

An excessively negative camber tyre will wear its inside edge faster, and excessive positive camber will wear the outside edge. Camber angles maintained within the manufacturer's specifications can avoid these problems.

DIY Camber Checks

Although a professional alignment is best, you can perform some simple checks yourself:

  • Visual Inspection: Stand in front or behind the vehicle and take a look at the lean of the tyres.

  • Use a Level: Hold a carpenter's level vertically up against the tyre to determine if it is leaning.

  • Tread Depth Measurement: Take readings of the tread depth at several points across the tyre. Different readings mean camber is out of alignment.

  • Camber Gauge: If you're more of a hands-on type, you can take a reading using a camber gauge and measure the precise angle.

Can Camber Be Adjusted at Home?

Some minor camber adjustments can be done at home, but camber settings usually need professional tools and expertise. DIY processes may lack the accuracy required, particularly if suspension parts must be replaced or adjusted. It is advisable to go to a professional alignment service for precise results.

Why Professional Alignment Matters 

Expert technicians possess equipment for proper measurement of camber and adjusting accordingly. Alignment shops commonly employ computerized machines that calculate the correct camber angle using your car's specifications.

Attempts at repairing camber without suitable equipment will result in improper settings, potentially aggravating the problem rather than fixing it.

Correct Camber Maintenance

It's a good idea to check your wheels alignment periodically, particularly after any collision or when you experience uneven tyre wear. Most professional alignments involve camber checks as part of an overall alignment package.

DIY Tips: 

  • Use a camber gauge if you feel confident in checking the angle yourself.
  • Do visual checks regularly, stand in front of your car and look at the tyre angle.
  • Don't ignore strange handling or tyre noise, these may be signs of camber problems.

Getting Professional Help

If you’re not sure about your camber alignment, it’s best to consult experts. Apollo Tyres dealerships offer professional alignment services to ensure your vehicle stays safe and performs well. Regular maintenance checks can help detect minor alignment problems before they become major issues.

A Final Word

Tyre camber is more than just a technical jargon, it's a critical component of your car's handling and safety. Knowing it allows you to maintain your car in optimal condition and prevent untimely tyre wear. Frequent alignment checks and maintenance are a big help in avoiding camber problems.

If you suspect your camber is out, don't wait, have it inspected by a professional. A minor tweak today can prevent greater issues tomorrow.
